In the days of yore, there was an HQP crash:
https://code.google.com/p/chromium/issues/detail?id=359270

I put a band-aid on the crash:
https://codereview.chromium.org/222783006

Later, I fixed the root cause:
https://codereview.chromium.org/255423002
Or at least I thought I did and close that days-of-yore bug.

Apparently this didn't entirely fix the problem.  (See the linked bug
below.)

This change adds some information to the minidumps to allow me to
investigate what kinds of inputs are causing trouble.
